With years of experience in honing tube manufacturing, we deliver customer satisfaction through both manufacturing and customization.
At Bos, we care about you and your company. We specialize in honing tube customization, material selection, and manufacturing, and we offer superior service tailored to your needs.




Optimized Seal Longevity and Reduced Friction: The uniquely cross-hatched surface pattern created by our honing process is engineered to retain lubrication. This creates an ideal running surface for piston seals, significantly reducing wear on the seal and the tube itself, thereby extending maintenance intervals.
Superior Value Proposition: Carbon steel offers an exceptional balance of strength and affordability. By employing advanced honing techniques, we elevate this material to a performance level that meets or exceeds the demands of most industrial applications, providing a cost-effective solution without sacrificing quality or reliability.
Enhanced Pressure Integrity and Structural Soundness: The seamless construction of the base tube, combined with the material properties of carbon steel, provides excellent resistance to deformation under high internal pressure. This ensures the structural integrity of the cylinder assembly throughout its operational life.
Exceptional Surface and Geometrical Precision: Beyond mere smoothness, our honing guarantees a consistent inner diameter with minimal deviation. This precise geometry ensures that the piston and seal travel without binding or creating uneven pressure points, leading to smoother operation and higher overall system efficiency.


What truly differentiates our role as a Carbon Steel Honed Tubes Supplier is our deeply ingrained culture of quality and technical collaboration. Our manufacturing process is vertically integrated and governed by a rigorous quality management system. We begin with a meticulous selection of raw materials, ensuring the chemical composition and integrity of the steel meet our strict standards. The subsequent honing process is conducted on state-of-the-art machinery operated by skilled technicians, allowing for precise control over surface finish and dimensional tolerances.
Our philosophy is one of partnership. Our engineering team possesses a profound understanding of how a Carbon Steel Honed Tube interacts with other components, such as a Hard Chrome Plated Piston Rod, within a sealed system. We engage with clients to understand their specific performance requirements, environmental challenges, and budgetary considerations. This allows us to recommend the optimal grade of carbon steel and the precise honing specification, ensuring a perfect fit for your application. Furthermore, our capability to provide custom-cut lengths and specialized end-finishing services means we deliver a component that is ready for seamless integration into your assembly line, reducing your production lead times and costs.

Honed tubes are finished using abrasive stones that create a precise, cross-hatched surface, while SRB tubes are processed using a cutting tool (skiving) followed by a burnishing roller. Honed tubes generally provide better surface finish and straightness, while SRB tubes can be more cost-effective for certain applications.
